Boston MBTA “Heavy Lift” Project: One Weekend, New Bridge

The MBTA is replacing the bridge carrying the Ashmont-Alewife Red Line over Clayton Street in the Dorchester neighborhood of Boston this weekend, November 8-11.

The $5.5 million project is the latest to be completed in one weekend using “heavy lift” accelerated bridge construction. MassDOT previously completed heavy lift bridge projects in Boston, Wellesley and Phillipston.

Accelerated bridge construction minimizes the duration of construction, increases safety, and dramatically reduces the duration of detours and rail service disruptions. MBTA contractors pre-assembled the replacement bridge on temporary supports at a staging area. This weekend, workers will demolish the old bridge. Then, special heavy lifting equipment and moving methods called Self-Propelled Modular Transporter (SPMT) will pick up the new bridge, carry it a short distance along Clayton Street and lower it into position.

Clayton Street will be closed for vehicle traffic on Friday, November 8, 7:00AM to Monday, November 11, 12:00 noon. Demolition of the bridge will begin at 9:00PM on November 8. The new bridge will be in place and open to rail service at 5:00AM on Monday, November 11.

Red Line service during the Veteran’s Day Weekend, November 8– November 11, between Ashmont and JFK/UMass will be replaced by bus service on Friday, November 8, 9:00PM to Monday, November 11, 5:00AM. The bus shuttle will serve Ashmont, Shawmut, Fields Corner, Savin Hill and JFK/UMass.
